Common Storage Units - JSS2 Computer Studies Lesson Note

  1. Byte: A byte consists of 8 bits and is the fundamental unit for representing characters, numbers, and other basic data. Bytes are the building blocks for larger storage units.

  • Kilobyte (KB): One kilobyte is equivalent to 1,024 bytes. Kilobytes are commonly used to measure the size of small text files, images, and simple documents.

  • Megabyte (MB): A megabyte is equal to 1,024 kilobytes or approximately one million bytes. Megabytes are used to describe the size of larger files, such as music tracks or high-resolution images.

  • Gigabyte (GB): A gigabyte is composed of 1,024 megabytes or approximately one billion bytes. Gigabytes are often used to express the capacity of hard drives, SSDs, and the memory of modern computers.

  • Terabyte (TB): One terabyte is equal to 1,024 gigabytes or approximately one trillion bytes. Terabytes are commonly used to quantify the storage capacity of external hard drives, data centers, and large-scale cloud storage solutions.
